rank insignias. The new rank insignia system was inspired from Royal Navy. The idea was that the British system was more internationally viable and thus would facilitate contact between officers. However, this drew some criticism as a commander with four galloons now got three galloons, which in the old rank insignia system was the rank insignia for lieutenant (kapten). Since the same date, a lieutenant has two instead of three galloons. Duties The lieutenant of a naval unit works as a commander, for example, a battle command officer, a second-in-command (sekond) or as a commander of a smaller ship. As a staff officer, the lieutenant has more advanced positions than the sub-lieutenant. The lieutenant is also suitable to serve both at the Swedish Armed Forces' schools or at the Swedish Defence University as a teacher or other position. The individual must be able to work as a teacher in officer training. The navy specifies a total period of service of six (6) years before it is time to become a lieutenant. Promotion According to Chapter 2, Section 1 of FFS 2018:7, a person who is eligible for promotion has served in the Swedish Armed Forces to such an extent that assessment of suitability, knowledge and skills could be carried out, is deemed suitable for promotion, possesses the knowledge and skills required for the higher rank, and meets time requirements according to Section 2 (must have held the rank for at least two years). For promotion from sub-lieutenant to lieutenant, it is only required that the sub-lieutenant is promotable according to Chapter 2, Section 1. Promotion of lieutenant to lieutenant commander may take place when the lieutenant has completed applicable promotion training with approved results. After completing a tactical staff course at the Swedish Defence University, a lieutenant who is OFSK may only be promoted to lieutenant commander with a passing grade if the position is within the functional area where the lieutenant's special competence is located, and if the position's rank code is OF 3. Responsible head of promotion to lieutenant is the unit commander. In the case of reserve officers, promotion of sub-lieutenant to lieutenant may take place if the sub-lieutenant holds an academic degree at the undergraduate level, or at least 180 credits if the program includes more than 180 credits. Promotion of lieutenant to lieutenant commander may take place when the lieutenant has completed applicable promotion training
